HOOP-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,1(34, dated August 2, 1881.

Application filed Ap1i127,1881. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER F. WARD, of Ghatham, in the county of Kent, Province of Ontario, Dominion of Canada, have invented an Improvement in Hoop-Ooilin g Machines, of which'the following is a specification.

The nature of this invention relates to certain new and useful improvements in a machine upon which hoops are coiled for shipment, and forwhich Letters Pa tent No. 223,968 were granted to me January 27 1880 and the invention consists in the novel construction of the various parts and their several combinations, as more fully hereinafter set forth.

Figure 1 is a front elevation, showing the machine in use in coiling hoops. Fig. 2 is a side elevation with the front standard and drum in vertical central section. Fig. 3 is a partial perspective of the main shaft and its to which motion is communicated through the pulley D from any suitable source of power. The pulley D is secured at the outer end of a counter-shaft, E, running in boxes a secured to the oscillating box F, the front end of which is pivotally secured to the frame A. A spring, I), one end of which is secured to the frame by the stud-bolt 0, passes rearward under the oscillating frame and holds it and the friction- 7 wheel H, which is also secured to the countershaft E from contact with the face of the drivprovided with an annular flange, (I, which is cut away at 6. Upon the rear face of the disk is secured the dog L by means of the screw f. A slot, M, is cut through the disk coincident with the cut-away portion of the flange thereon, and the dog L is compelled by the spring gto close against the inner face of the flange, as shown in Figs. 1 and 3, except when forcibly disengaged, as hereinafter described. The dog is provided with an L-shaped arm, h.

Upon the shaft B there is sleeved a spider, N, provided with arms '11, to the outer ends of which is secured the ring 0, of a larger diameter than that of the coiling-disk K. The hub l of this spider is cone-shaped at its forward end, so that when the spider is projected forward for the purpose of compelling the annular ring 0 to push the coil of hoops from the periphery of the coiling-disk the conical portion of the hub will actuate the arm h of the dog, and compel the dog to overcome the resistance of the spring 9 and release the end of the hoop m which has been held by the dog against the inner side of the flange of the coiling-disk, as shown in Fig. 1.

Instead of the hub being cone-shaped, as shown in the drawings, its end may be curved, or it may be left square, and the end of the arm h of the dog may be curved or beveled, or both the arm hand the end of the hub may be curved or beveled to produce the desired operation of the dog.

To the rear end of the spider N is secured the curved lever a, the other end of which is pivoted to the bell-crank 0, which is pivotally secured to the frame, and to this bell-crank is also pivotally secured a rod, 10, the other end of which is pivotally secured to the guardfinger P. Another rod, 4, is also pivotally secured to said guard-finger, and the opposite end of this latter lever is pivotally secured to the crank s, which is secured to one end of the roclrshaft t, to whichis secured the treadlelever B, to the opposite end of which is secured the weight S. By this system of levers, unless a weightfiis imposed upon the treadle R the weight S holds the spider N with its hub in a retracted position, as shown in Fig. 1, and the guard-finger P in the position there shown; but if the foot is placed-upon the treadle R to overcome and raise the weight S, the spider will be projected, as shown in dotted lines, to force the hoop-coil off the disk,simultaneously throwing down the finger-guard to allow the hoop-coil to be thus thrown off.

A plate, T, is pivotally and adjustably secured to the front of the frame at u, and by means of a bolt, 2', a strap, U, is secured to this plate, and the other end of this strap is similarly secured to the weighted lever Y, which is fulcrumed at .r to the top of a projection of the frame A. The opposite end of this lever V is provided with a weight, \V, the lower edge of which may be provided with a butter-spring, 20, if desired. To a stml-projection, y, from the frontofthis lever, is pivotally secured the guardbar Y, the lower end of which passes through the guide The strap or band U may be made of a single piece of suitable material, or it may be made in segmental sections pivotally secured together at their ends by means of the cars a, which, in coiling, embrace the hoop and guide it.

In practice, with the machine constructed and arranged substantially as above described and the parts in position, shown in Fig. 2, the end of the hoop is inserted under the toe of the dog L. The machine is then started by depressing the lever I, causing the friction-pulley II to come in contact with the drivingwheel 0, thus imparting a rotary motion to the coiling-disk and a consequent coiling ot' the hoop upon the periphery oi'the disk, and against which it is held by the band U, the weighted lever V securing the proper tension, while the free end of the hoop is kept from flying up by the nipper D which is adjustably secured upon the front face of the plate T. The end of the next hoop presented is inserted under the end of the coiled hoop, and so on until the coil of hoops is as large as desired, the end of the last hoop being kept down upon the coil by the nipper I), and can thus be easily nailed. Then pressing upon the lever It the spider will be projected, causing the hub of the spider to release the dog and the ram to force the coil of hoops off the coiling-disk, the guard I beingsimultaneously depressed with the advancement of the ram. By ieleasing the lever It the various parts resume their original positions preparatory to forming another coil, if so desired.

The swinging plate T is adjustable upon its pivot to for the purpose of adjusting the distance between the swinging plate T and guardbar Y to the width of the hoops operated upon.

hat I claim as my invention is 1. In a hoop'coiling machine, and in combination with the coiling-disk, holding-dog, mechanism, substantially as described, for operating said dog, and pulley O, the friction-wheel H, pivoted box F, carrying said wheel, spring b for raising the pivoted box and friction-wheel from the pulley C, and the connecting-rod J and treadle I for bringing the wheel in contact with the pulley, as and for the purpose specifled.

2. In a hoop-coiling machine, and in combition with the coiling-disk K and pivoted dog L, having an arm, h, the sliding hub I, either or both the sliding hub and arm it, having a, curved or beveled end, substantially as and for the purpose specified.

3. In a hoop-coilingmachine, and in combination with the coiling-disk K, holding-dog L, arm h on said dog, and the hub I, either or both the hub land arm it having a curved or beveled end, the spider N, sliding on the main shaft and carrying the huh I, whereby the hoop is released from the dog and forced otf the coiling-disk simultaneously by the treadle and connections, substantially as described, between the treadlc and spider, substantially as set forth.
